Action

Notice of proposed rulemaking; reopening of public comment period. -----------------------------------------------------------------------

Summary

On January 21, 2026, the U.S. Department of Energy (``DOE'') published a notice of proposed rulemaking (``NOPR'') seeking to amend certain regulations for worker safety and health to expedite the review, approval, and deployment of advanced reactors under DOE's jurisdiction, including qualified test reactors in DOE's reactor pilot program consistent with a recent Executive order. The NOPR provided an opportunity for submitting written comments, data, and information by February 20, 2026. By letter dated February 4, 2026, the American Federation of Labor and Congress of Industrial Organizations (``AFL- CIO'') requested a 45-day extension to the comment period. DOE has reviewed this request and is re-opening the public comment period until March 23, 2026.

Dates

The comment period for the NOPR published on January 21, 2026 (91 FR 2498) is reopened. Written comments, data and information regarding the NOPR will be accepted on or before March 23, 2026.

Supplementary Information

On January 21, 2026, DOE published a notice of proposed rulemaking (``NOPR'') that would amend its regulations for worker safety and health contained in 10 CFR part 851 (Worker Safety and Health Program). The proposal sought to revise these regulations to enable DOE to expedite the review, approval, and deployment of advanced reactors under DOE's jurisdiction, including qualified test reactors in DOE's reactor pilot program. These actions would be made consistent with Executive Order 14301, Reforming Nuclear Reactor Testing at the Department of Energy, which was issued on May 23, 2025. (90 FR 22591) The NOPR sought comment on the proposal by February 20, 2026 By letter dated February 4, 2026, DOE received a request from the American Federation of Labor and Congress of Industrial Organizations (``AFL-CIO'') seeking a 45-day extension to the comment period. The AFL-CIO asserted that the potential effects of DOE's proposed rulemaking are complex in nature and that additional time is needed for careful review and coordination across the organization's various affiliates to establish thorough and informed comments.\1\ --------------------------------------------------------------------------- \1\ DOE is also aware of at least two other requests for additional time. --------------------------------------------------------------------------- DOE has reviewed the request and considered the benefit of allowing interested parties additional time to submit comments regarding the January 2026 NOPR. Accordingly, while DOE is confident that the AFL-CIO and other commenters had sufficient time to provide complete comments by February 20th, DOE is reopening the comment period until March 23, 2026.
